A team of scientists has successfully extracted the woolly rhinoceros' genetic material from a 14,400-year-old meal mummified in the stomach of an ancient wolf cub found in Siberia. The discovery provides valuable insights into the final years of this prehistoric species.
Researchers used a cutting-edge technique to decode the DNA from the preserved remains of the young wolf cub, which was unearthed near the village of Tumat in northeastern Siberia. The analysis revealed that the population size and genetic diversity of the woolly rhinoceros remained relatively stable before its sudden disappearance around 14,000 years ago.
The findings contradict the common assumption that species in decline lose genetic diversity due to factors such as population bottlenecks, inbreeding, and environmental pressures. Instead, the researchers discovered that the woolly rhinoceros' genetic material showed signs of a relatively fast extinction event, with the population size dwindling within 300-400 years.
The data suggests that the primary cause of the species' demise was not hunting by early humans but rather an abrupt period of warming in the last ice age. This phenomenon, known as the Bølling-Allerød Interstadial, altered the landscape between 14,700 and 12,900 years ago.
The discovery is significant, providing a rare glimpse into the final days of this Ice Age species. The researchers found that woolly rhinos may have had a viable population for approximately 15,000 years after human arrival in the region, underscoring the impact of climate change on these ancient creatures.
